The objective of this study was to determine the hematological values of Brycon amazonicus broodstock under culture in Iquitos, Peru. Blood samples were taken from 12 specimens (1.62 ± 0.45 kg and 51.38 ± 2.93 cm) maintained in earthen ponds and fed twice a day with a commercial diet with 22% crude protein. The fish were collected with a net and anesthetized with eugenol. Blood extraction was performed with disposable syringes containing EDTA (10%). The values obtained from the erythrocytic series were: hematocrit 53.3 ± 4.8%; hemoglobin 20.1 ± 3.2 g/dl; erythrocytes 2.8 ± 0.5 x106/μl; VCM 194.4 ± 54.4 fl; CHCM 37.7 ± 4.8 g/dl; HCM 72.6 ± 17.7 pg. The number of leukocytes was 8.1 ± 6.0 x103/μl. In the differential count of leukocytes, the lymphocytes and monocytes had greater proportion in comparison with neutrophils, eosinophils and basophils. The total serum protein was 3.7 ...
